I think you've got a good start. On the Egyptian one at top, I'd make the eyebrows a bit thicker. Stark works well for the look, but they seem thin to me. For both of them, I think they would benefit from a little more toning. Think of the parts of the body that get a lot of bloodflow, like the cheeks, nose and forehead, the palms of the hand, the breasts and so on, and add some pink undertones to those areas. You do have a very nice start, though. They already look better than many finished textures I've seen.
